Hi all, wasn't sure whether to post this in conception or pregnancy. We're looking at TTC soon. We have a non-refundable holiday booked but depending on how long it takes to conceive, it may end up being that my 20 week scan is due whilst we're on holiday. 1st month trying would be fine but 2nd month would mean 20 week scan is when we're abroad and if dates stay the same, could even be my 12 week scan if we conceive on cycle 4. I don't really want to delay trying for another 4 months just in case and I know ovulation dates can change and TTC is a case of how long is a piece of string in terms of how long it takes, but I've been having pretty regular periods and ovulations (I track via BBT and CM) so if we did conceive in those months, it's likely scan would be due when we're not here. If it did happen, how much of an issue would it be in terms of late / early scans? First time trying so don't really know how likely it is scans are at the right time.
